In AC electrons oscillate. In DC electrons are flowing for ages.
Where they come from?


No; in AC electrons periodically change directions and in DC electrons
flow in one direction only.

An antenna is a device that converts the electromagnetic energy which
antenna intercepts
into AC electrical energy at it's terminals.

A diode converts AC into DC.


The crystal radio antenna has only one terminal. Before the diode is AC.
After the diode is DC.
Where electrons come from?
